Drain Mats/Covers

clay dammit, mechanical, polyurethane reusable drain mats in use

We sell a range of drain mats and covers to seal your drains in the event of a spill to prevent contaminants from escaping site and polluting the environment or local sewage treatment facility.

Clay Drain Mats

We provide clay drain mats in a variety of sizes to instantly seal a drain. Our drain mats fit the contours of drains to create a complete seal on uneven or broken drains. Due to their flexibility you can easily seal misshapen drains.

Our range of clay products are a high performing and cost effective method of blocking drains and preventing spilled fluids entering the drainage system. Dammit mats are treated with a formula which prevents mould growth and anti-freeze properties so the mat remains flexible down to -20c.

  • The most effective low cost drainseal on the market
  • Sized to fit most drains, although several mats can be utilised on the same drain if one doesn't completely seal it.
  • This product gives 100% seal even on rough surfaces
  • Remains flexible down to -20c
  • non toxic and bio inert
  • Resistant to oil, water and most chemicals
  • Simple to use - peel off cover and tread onto drain.

Polyurethane Drain Covers

Polyurethane drain covers offer quick deployment and a cost effective method of preventing contaminants getting into the drainage system. These reusable drain covers are manufactured in polyurethane for strength and flexibility and are resistant to oil, water, fuel and most chemicals. The contact side of the drain cover is sticky creating an effective seal to the contours of the drain and surrounding ground.

Our drain covers are bonded to a nylon sheet providing extra strength and visibility. Our polyurethane drain mats come in two thicknesses, 8mm for standard pollution incidents and 13mm for severe flood situations. If deployed, once pollution risk has been resolved, simply clean the drain cover and store ready for next use.

  • A tough durable yet flexible drain cover that moulds and sticks to the contours of the drain
  • Resists oil and most chemicals
  • Sized to fit most drains
  • Can be re-used

Mechanical Drain Seals

Mechanical drain seals clamp onto the drain and will not lift no matter how much liquid surrounds it and will stay in place even with back pressure. Our drain cover seals are available in three standard sizes to suit most drains.

  • Come in three standard sizes to suit most drains
  • Are reusable for deployment in high risk areas
  • Create a 100% seal to drain grid forming a bunded area
